Application filed August 2. 1893- Serial No. 482,150- (No model.)

7 To 00% whom it may concern:

Be it known that I, GEORGE W. RAYMOND, a citizen of the United States,residing at Seneca, in the county of La Salle and State of Illinois,have invented a new and useful Draft-Equalizer, of which the followingis a specification.

My invention relates to an improved fourhorse draft-equalizer welladapted for use with plows.

The invention will first be described in connection with theaccompanying drawings, and then pointed out in the claims.

Figure l of the drawings is a plan view of my improved draft-equalizerattached to the beam of a plow. Fig. 2 is a vertical section taken onthe line w m, Fig. 1. Fig. 3 is a broken perspective view, showing themeans of attaching the draft-bar to the plow-beam. Fig. 4 is a verticalsection taken on the line 1! y s- Referring to the drawings, A isthe'drawplate, composed preferably of a narrow strip of iron, or othersuitable material, having holes 1 located therein, as shown, andattached to the plow-beam B in the following manner: A draft-pin a ispassed through a clampO, which has its ends turned up at right angles tothe plane of its length, and is securely fastened to beam B by a bolt 6.The pin then passes through a tubular washer c; then through thedraw-plate A, the washer serving to keep the clamp and the draw-platethe proper distance apart. On the draft-pin a, beneath the draw-plate A,there is pivoted the rear end of a V-shaped brace D, whose divergingouter ends are preferably turned up at a right angle and given a halftwist, they having bolt-holes 2, through which passes the bolt d, thelatter serving also to secure the plow-beam head B to the beam B. Thisbrace serves to keep the draft-pin steady and prevent the pull on thedraw-plate A from drawing it out of its perpendicular position. On thescrew-threaded lower end of pin a there is a nut, serving to keep allthe above parts together.

To the beam-head there is attached, by means of a flexible connection,preferably a pin and link E, as shown, a clevis F, to which there isremovably secured, by a bolt e and a nut a, what I term the equalizer G,the bolt being passed through from the under side and countersunk in theclevis. In the equalizer, in a longitudinal line with the clevishole andequidistant from each other, there is a plurality of holes, by means ofwhich the position of the clevis F may be changed, for a purposehereinafter explained.

To one end of and beneath the equalizer G there is pivotally secured, bymeans of a bolt fand a nut f, an evener H. A washerf is placed on bolt fbetween the equalizer G and the evener H, this washer being of such aWidth as to prevent the evener H, in passing under the equalizer G, fromcoming into contact with clevis F. To the other end of and above theequalizer G there is pivoted one end of a lever I, these two parts beingseparated by a washer g on the bolt 71, which connects equalizer G andlever I, so that the lever may swing clear of the upper part of clevis Fand nut f on boltf. In the outer or free ends of the evener II and leverI there are formed a series of holes 3'and 4, respectively. In one ofthe holes 3 in the evener there is removably secured a clevis J, and inone of the holes 4 in the lever there is also removably secured asimilar clevis J, these clevises engaging with hooks j and respectively,which hooks are connected with the forward ends of draft-chains K and K,said chains carrying at their rear ends hooks k and k, respectively,which engage with holes lin draft-plate A.

Ordinary doubletrees L and L are removably secured, through links M andM, to the outer ends of the evener H and lever I, re spectively, bymeans of bolts passed through either of the holes in those parts.

The operation of my equalizer is as follows: If the excess of draft ison the chain K, that end of the plate A to which that chain is attachedwill be drawn in the forward direction and thepther end of thedraw-plate will be moved backward, carrying with it draftohain K, whichwill draw the outer end of the lever I with it. As the lever, pivoted tothe end of link M, moves backward the other end will move forward,carrying with it the end of the equalizer to which it is attached, andsending the other end of equalizer G backward. As the evener H isattached to the end of equalizer G, it will be carried backward, whichwill move the clevis J and chain K in the rearward direction, tending toallow the plate A to resume its normal position and thereby draw theplow perfectly true. As the excess of draft differs with differentteams, and as the amount of motion given the various parts in tending toequalize the pull, as above explained, depends on the location of thevarious clevises, hooks, &c., the equalization can be easily eifected inany of the following ways: by changing the point of attachment of linksMor M in the evener or lever; by changing the point of attachment of theclevises to which the hooks j and j of the draft-chains are attached; bychanging hooks k or k to any of the other holes in plate A, therebyaltering the leverage on that plate; or by changing the pivotal supportof the equalizer, by moving the clevis F to any of the other holes inthat part.

While I have shown and described my invention as applied to a plow, itisevident that it may be used with such other implements, Wheeledvehicles, sleds, &c., as have a draft beam or pole.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a draft-equalizer, the combination,

with a draft-beam, of a draw-plate pivoted to said beam, an evener, anequalizer pivoted at one end to one end of said evener, a lever pivotedat one end to the other end of the equalizer, a clevis connecting theequalizer with the end of the draft-beam, chains adjustably attached toand connecting the drawplate and the evener and lever, and double treesadj ustably attached to the evener and lever, respectively,substantially as described.

2. In a draft-equalizer, the combination, with a plow-beam provided witha removable head, of a clamp secured to the under side of said beam, adraw-plate, a draft-pin conmeeting said plate and clamp, a washer,between the draW-plate and clamp,a pin-brace connected at one end to thedraft-pin and at the other end to the beam-head, an evener, an equalizerpivoted at one end to one end of said evener, a lever pivoted at one endto the other end of the equalizer, a clevis connecting the equalizerwith the beam-head, chains adjustably attached to and connecting thedraw-plate and the evener and lever, and doubletrees adj ustablyattached to the evener and lover, respectively, substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

GEORGE W. RAYMOND.
